Transformer tank wall making machine is used to make corrugated cooling wall for oil filled power transformer.
Transformer tank wall as the key part of oil immersed transformer tanks, core is inside the transformer cooling oil. Transformer tank provides isolation of oil and the core from outside environment and is used for cooling process. Corrugated fin walls (transformer tank wall) or radiators are used as cooling elements in transformers.
welded corrugated finwall by JTFY auto fins wall seam welding machine
Hydraulic Decoiler used to hold and feed steel roll to Corrugated fins wall making machine with suitable speed automatically. Corrugated fins wall making machine Press, Fold and Forming Steel sheet to required dimensions.
This machine controlled by PLC, all key hydraulic,pneumatic, electrical elements adopt BEST Famous brands. Key mechanical structure use STANDARD QT500 CASTING IRON PARTS.To insure whole machine with high precision, long life and stable in working.
As one part of the Full Automatic Corrugated Fins Wall Production Line, Transformer tank wall making machine is the key machine in whole process.
Corrugated fin forming length 300-2000mm, width 300-1300mm, height 50-400mm, with embossing and spot welding function.
1) Model and name: JTFY1300-400 Automatic Column Corrugated fin Wall Forming Machine / Folding Machine
2) Standard configuration: PLC touch screen Fullauto control and manual control.
PLC and touch screen brand:MITSUBISHI / OMRON / DELTA

3) Hydraulic part: Motor Power 18.5KW, pressure adjustable. The effective total flow is higher than 100L/min.
4) The mechanical structure of forming machine involve: guiding structure, hydraulic forming, hydraulic shearing etc. Whole machine design structure is reasonable, easy for operating, adjusting and maintenance.Machine body adopts frame-box structure, movable die, column and other parts are all used ductile iron castings(STANDARD GB QT500), with anti-angular distortion and partial loading performance, and at the same time, it has related strength, rigidity and precision.
5) Guide rail of main moving direction (front and back) in hydraulic forming components adopts quenching anti-wear steel rail, up and down moving plate adopts casting iron guide, connecting smoothly, high guiding precision, sensitive movement, low noise, long using life and other characteristics.
6) Shearing structure is herringbone blade, stable shearing. Fin head and end length can be set, shearing automatically.
7) Material feeding adopts XINJIE servo motor with high precision planetary speed reducer and tested by encoder, so feeding precision is higher.
8) Material unrolling shelf adopts automatic mandrel core expanding structure, it can make roll tightly and fix the core. Suitable for internal diameter of 520mm(MAX.), roll width 1300mm, can load 10 tons.
9) Equipment has safe device with emergency stop button in many places. Different place can be stopped in urgently, and have overloading protection.
